LibBPQ logs most bits to /var/log/syslog

This also includes some very chatty 'Heartbeats'

May 13 22:38:39 linbpq_box1 LINBPQ[5905]: BPQ32 Heartbeat Buffers 998 APRS Queues 0 0#015

To save SD card writes, you can re-direct this out to RAM (/run - or somewhere else that is RAM on your system)

To do this, you need to create a new file

/etc/rsyslog.d/00-linbpq-buffers.conf

and add to it:

if $msg contains 'BPQ32 Heartbeat' then /run/linbpq-buffers.log
& STOP

( note, if you are on an older version on rsyslog, you need & ~ instead of & STOP )

Then restart rsyslogd

sudo systemctl restart rsyslogd

This may fill up your RAM, so you can do several things

• Create a CRON job to delete this file (or archive it etc)
• use logrotate

To use logrotate, to compress the files and only keep 7 days:

Create a file

cat /etc/logrotate.d/linbpq-buffers

Add this to the file

/run/linbpq-buffers.log {
     rotate 7
     daily
     missingok
     compress
}
